The flash point of a volatile material is the lowest temperature at which vapors of a fluid will ignite. Measuring a flash point requires an ignition source. At the flash point, the vapor may cease to burn when the ignition source is removed.
The flash point is not to be confused with the autoignition temperature (which does not require an ignition source) or with the fire point (the temperature at which the vapor continues to burn after being ignited).
